Keep cabin airflow and temperature blending under control with the Dorman - OE Solutions HVAC Blend Door Actuator 604-211. This small electric motor drives an HVAC air door, positioning it to route and mix airflow inside the heating and cooling system. It installs as a direct-fit replacement for the auxiliary actuator position on the 2002-2010 Ford Explorer, 2003-2005 Lincoln Aviator, and 2002-2010 Mercury Mountaineer.
Key features:
- Direct replacement — engineered to drop in like the original air door actuator on the listed applications and restore proper HVAC operation.
- Position specific — this is the auxiliary actuator; many vehicles use several HVAC door actuators, so review the application notes to confirm it matches the location and function of the one you need to replace.
- Durable construction — designed and tested to strict standards to help resist wear and electrical burnout for reliable operation.
- Trustworthy quality — backed by engineers in the United States and more than a century of experience.
Signs the auxiliary actuator may need replacing include clicking or knocking from behind the dash, airflow stuck on one temperature or vent setting, and no response to climate control changes. If a failed blend door actuator is the cause, this unit replaces it.
